Strap for Superocean 42 Stainless Steel / Black / Rubber - Folding / Japan

The Breitling Superocean A17366D71B2S2 has a lug width of 20mm. This measurement should be taken with a digital calliper at the widest point of the gap between the lugs, perpendicular to the case-strap axis, to ensure accurate compatibility with any aftermarket strap.

The ideal choice depends on the intended context. For formal settings, a vegetable-tanned alligator strap in cognac or gloss black complements the black dial without undermining the watch's sporting character. For daily use or humid environments, waxed calfskin or vulcanised rubber offer durability and comfort. A two-tone ballistic NATO strap remains the most faithful option to the model's instrumental heritage.

The strap is removed using a spring bar tool or a dedicated hook-end tool to compress the spring bars securing the strap to the lugs. Work on a soft surface to protect the caseback and lug finishing. Original Breitling spring bars are compatible with standard 20mm fittings; however, when fitting a heavy leather strap, it is advisable to replace them with reinforced 1.5mm stainless steel spring bars.

Yes. Any strap with a 20mm lug width and tapered or sufficiently supple ends is compatible. Casati Milano produces aftermarket straps shaped to the original Breitling Superocean lug geometry, with a pre-curved taper ensuring a flush fit without lateral stress. Compatibility extends to standard 18mm buckles or 20mm deployant clasps.

Longevity depends on the leather type and conditions of use. A vegetable-tanned calfskin strap, with proper care (avoiding prolonged water exposure and conditioning periodically with a neutral product), maintains structural integrity for 2–4 years of daily wear. Shell cordovan, owing to its dense, compact fibre structure, can exceed 5 years. For sporting or humid-environment use, rubber or nylon is recommended, as neither is susceptible to hydrolytic degradation.
